What is the difference between an extraction condensing unit and a back pressure unit?

1. The exhaust steam of the steam turbine of the back pressure unit is positive pressure exhaust steam, and the exhaust steam is sent directly to the heat user. Unfinished steam from the extraction condensing unit is extracted from steam. turbine extraction port and sent to hot users.

2. The size of the power generation load of the back pressure unit is directly related to the size of the heat supply. Once the steam turbine continues to operate, the remaining parts of the extraction condensing unit are. discharged into the condenser to condense into water, then return to the boiler.

3. The operating mode of the back pressure unit is rigid, while the operating mode of the extraction condensing unit is flexible and is less limited by the heating load.

The extrac condensed steam turbinetion is actually a combination of a condensing steam turbine and a counter-pressure steam turbine.

Detailed information:

A generator refers to a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power source. Machines for converting water and air flow. , the energy generated by fuel combustion or nuclear fission is converted into mechanical energy and transmitted to the generator, which is then converted into electrical energy by the generator.

Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. There are many forms of generators, but their operating principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: using suitable magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction among themselves to generate electromagnetic energy and achieve the goal of converting energy.

What are the requirements for back-pressure generator sets when connected to the grid?

60 kW generator and 25 kW generator. Variable frequency starting method: 3000 counter-pressure steam turbine is equipped with 18 kW generator, 3000 counter-pressure steam turbine is equipped with 25 kW common generator; direct start mode: the 3000 counter-pressure steam turbine is equipped with a 60 kW generator; The 3000 counter-pressure steam turbine is equipped with a common 60 kW generator.

The engine which mainly drivesnt the diesel engine of the counter pressure generator set is the counter pressure steam engine. Its connection conditions to the network are the same as those of other generators:

1) The order of the phases must be the same as that of the network;

2) Its voltage must be the same as the network voltage

3) Its frequency must be; the same as the grid frequency, and the phase of the voltage must be consistent with the phase of the grid voltage.
